Letters Patent No. 114,482, dated May 2, 1871 IMPROVEMENT IN APPARATUS. FOR @TOMIZING LIQU IDS.

The Schedule referred to in these Latters'Pateni: and making psxt of the same.

To all whom it may concern Be it known that I, ASAHEL M. SHURTLEFF, of- Boston, in the county of Sufiolkand State of Massachusetts, have invented certain Improvements in Atomizing Apparatus; and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention sufiicient to enable those skilled in the art to practice it.

My invention has reference to the construction of that class ofhand-operating atomizing apparatus in which the current of air is supplied to the air-tube of the atomizer by means of a flexible elastic bulb, theinvention relating principally to details of construction and relative arrangement of the parts.

In constructing the improved apparatus I employ, preferably, a bulb formed ofcaoutchouo compound, and having a base or foot fixed to one end of it, or formed with or as a part of it, the opposite end of this bulb having a neck, into which is inserted or upon which'is fixed one end of a metal valve and air-induction and eduction-box or tube, through which box or tube .is made an air-inlet, and from which box or tube the air-eduction atomizing-tube leads, said box'being provided with a valve-seat and valve, which permit free ingress of air through the box into the bulb, but which prevent exit of the air except through the atomizing-tube.

1n axial line with the bulb, and at some distance above or beyond the valve-box or tube, is the liquidcontaining cup or vessel, and from thegoutermost end of this vessel extends the liquid-atomizing tube, (or

the liquid-tube of the atomizer,) the'cup being con nected to the tube by a screw-cap or coupling, and

the cup and liquid-tube being connected with and atmatched to the bulb or its valve-box by the air-tube of the atomizer, which tube is bent to enable the parts to be maintained in proper relative position.

The invention consists in an elastic bulb constituting the base of support'of the atomizing apparatus; in the construction of the bulb with an integrally-formed base or foot; in the combination with the bulb ot a metal valve-box or valve-tube, through which air is both drawndnto the elastic bulb or pump and ejected from\said pump; in the direct combination with the atomizing-tube or tubes of the valve-box; in the connection of the liquid-vessel and the bulb, through the medium or" the atomizer-tubes and valve-box; in the arrangement of the air-pumpor elastic bulb and liquidcup in axial line; and in certain other details of construction.

The drawing represents an apparatus embodying my improvements.

A shows the apparatus in side elevation.

Bis aside and sectional elevation of it.

a denotes the bulb, havinga base or foot, I), preferably formed as a part of or molded upon one end of the bulb, although it may be attached thereto by a suitable pin, this base or foot enabling the bulb and atomizing-tubes to stand upright, as shown at A.

0 denotes the air-tube, and

(l the liquid-tube of the atomizer.

The air-tube'c extends directly from the upper end of the bulb a, or preferably from a couplingtube, 0, attached to the top of the bulb.

This tube e is preferably the air-inlet and outlet, for which purpose it is provided with an air-induction orifice, f, and'an air-eduction'orifice, 37, (leading into the air-tube 0,). and betweentheseihlet and outlet-orifices is placed a'valve, 71, the under sideof' a screw-cap, t,

.(through which the orifice f is made,)' constituting the valve-seat.

The bulb is attached to the valve-tube by means of a nipple, k, at the lower end of the valve-tube, as seen at B.

2 denotes the liquid-containing vessel, preferably placed inaxial line with the bulb, and between the bulb and the liquid-tube d The liquid-vessel is connected to the tube Z by a screw-cap or connector, m, to which is fixed and through which extends the tube d,\ aud above the cap m the atomizing-tubes 0 d are connected, their atomizing-orifices being relatively arranged in the usual manner.

Thetube cextends from the valve-tube orbox e by the side of the vessel to the tube'd, and it, or it 'and the tube at, forms the connection between the bulb and the liquid-vessel.

The tube at ora projection from it may extend down to the valve-tube 0, but the connection shown is preferable.

The screw-cap m is provided with an orifice, o, by which air can enter the cup or vessell as the liquid is drawn therefrom and to prevent leakage when the atomizer is not in use, and to regulate the force or amount of spray ejected at the atomizing points the screw-threaded neck 1) of the liquid-vessel is made to screw up into the cap in such manner that the airorilice may be enlarged or contract-ed, or may be en- :tirely closed, in which latter case no leakage can occur, even though the instrument be laid upon its side in a trunk or a bureau-drawer. I

To obtain the requisite size in the liquid-vessel I form such vessel of frusto-conical shape, or enlarging from the neck to the base, and to enable the liquid to be exhausted from thevessel the tube (Z is provided with a flexible continuation, q, the'end of which being weighted forces the mouth of the tube 9 to the lowest part of the vessel by gravity when the instrument is used in horizontalal position, as seen at B, thus enabling all the liquid to be drawn out.

It will be observed that the air. drawn in at the orifice f passes directlyby the eduction-orifice g, so

that any foreign matter collecting about the eductionorifice will be dislodged by the current of air and prevented from entering the air-tube c and clogging the air-passage.

The apparatus thus made or arranged is exceedingly compact and convenient to use, and no care is needed to keep the parts in place.

The liquid-cup is shown as connected to the tube (1 by a screw-threaded metal connection. Instead of such arrangement an elastic stopper maybe used, the vessel being )ressed upon the stopper and sprung into place betwee itand the tube 0, the vessel being then held in place by the elasticity of the stopper and by scribed.
